This compensates for the flow resistance of the heat exchanger or radiator, so as to keep the overall flow rate V 100 as constant as possible.

6 We recommend installing the valves in the return pipe, as the temperatures are lower for applications in heating systems, which in turn, extends the stem sealing gland's life. Recommendation: lways use a strainer upstream of the valve to increase the valve's functional reliability. Mounting notes oth valve and actuator can easily be assembled at the mounting location. Neither special tools nor adjustments are required. The valve is supplied with Mounting Instructions Orientation Z01 Commissioning notes Commission the valve only if the manual knob or actuator have been mounted correctly. Manual adjustment The straight-through path can be opened electrically via the actuator, or manually. With three-port valves, this throttles or closes bypass. Manually, path can only be opened to 70 % (bypass closes to 30 %). The valves with k vs values 10, 16 and 25 can be fully opened whereas the bypass can be fully closed. The valves are closed by a return spring. Maintenance V..P45.. valves require no maintenance.. Warning When doing service work on the valve or actuator: Deactivate the pump and turn off the power supply Close the shutoff valves Fully reduce the pressure in the piping system and allow pipes to completely cool down If necessary, disconnect the electrical wires. efore putting the valve into operation again, make sure the manual knob or the actuator is correctly fitted. Stem sealing gland The stem sealing gland cannot be exchanged. In the case of leakage, the entire valve must be replaced. Contact your local Siemens representative or office. Disposal efore disposal the valve must be dismantled and separated into its various constituent materials. Legislation may demand special handling of certain components, or it may be sensible from an ecological point of view. Current local legislation must be observed.
